boiler of 4 5 tons steam boiler gas oil
Improve the thermal efficiency of gas boiler of 4 5 tons steam boiler oil steam boiler to improve the thermal efficiency of gas is a problem many users are taken, I believe this issue is the direction of each used in the production of various types of gas steam boiler manufacturers have been in the study. Many users at the time of the gas-steam oven operates, often in the actual production process, we found some new problems, but all the problems, the most vexing is the high temperature exhaust gas steam boilers, thermal efficiency than low phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to know this is the best way to meet the low-temperature properties of gas and steam comes as synthetic gas steam. However, the vast majority of synthetic gas and steam biphenyls, benzene derivatives of both components of the complex, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended that the client select the type of mineral oil vapor product gas. Second, gas and steam products to meet the low temperature performance process, but also have a relatively high flash point required. In general, gas steam engineers suggest, low temperature gas steam flash point not lower than the opening 200 ℃. After a professional manufacturer of continuous research and improvement of its equipment, in order to improve its thermal efficiency was found to be increased tail gas steam boiler heating surface of, say, air preheater and economizer. But when organic heat carrier furnace return temperature is high, you can not set the economizer, air preheater can only be set to alleviate the situation. So if no gas steam boiler and other heating systems for low temperature heat exchanger, then the only way to improve the energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in gas flow rate of steam, gas steam boiler in order to ensure safe, reliable and stable work, the thermal efficiency of gas-steam boiler plant will be a corresponding with the increase.
Pressure boiler furnace designed to fully consider the characteristics of the fuel pressure boilers body member are two main drum and furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The overall structure of pressure boilers and boiler auxiliary equipment including two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.
A heated boiler is called a boiler. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as intermediate heat transfer medium in industrial heat transfer for more than 50 years. Based on the idea of forced cycle design, a once-through boiler is developed. Generally, coal, oil and steam are used as fuel, heat conduction oil is used as the medium, hot oil circulation pump is used to force the medium into liquid phase circulation, heat energy is transmitted to the heating equipment and then returned to the heating furnace for re-heating. High operating temperature at low pressure, and high precision control for medium operation. The heat utilization rate of the system is high, and the transportation and maintenance are convenient. The closed circulation heat supply is connected with the atmosphere, can extend the service life of the boiler, liquid phase or gas phase transportation heating. The boiler adopts three-way coil design, the system sets the expansion water tank, and realizes low-pressure and high-temperature heating. The coil structure is adopted, the heating surface is sufficient, and the expansion is fully absorbed. Imported low-NOX combustion machine, combustion charge, belongs to environmental protection products. Boiler can choose advanced touch screen computer controller and digital computer controller automatic control system. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, quenching protection. Boiler manufacturing standards, strictly in accordance with the relevant national standards. Pot The use of furnace water quality requirements: some users believe that as long as the boiler to maintain water can be, the water quality is not a choice. In fact, the quality of water on the boiler or have an impact, the editor recommends that you choose clean tap water. Because if there are impurities in the water, the use of this impurity water will have some impact on the equipment. The impurities form a thick layer of scale on the inner wall of the boiler. Scale will gradually thicken with time, and the accumulation of thickness will affect its heat transfer efficiency, resulting in a waste of energy consumption. If the scale appears, it should be cleaned up in time, so that the heat can be concentrated in the scale, which is not easy to emit. .
Hebei province is the use of industrial boilers, countless large and small boilers, air pollution caused by coal-fired boiler is one of the problems of governance in Hebei Province, and therefore become a major coal-fired boiler control of air pollution in Hebei Province direction. Coal-fired auxiliary boiler control work steadily, the Hebei provincial government to develop a "" comprehensive management of air pollution in Hebei provincial financial assistance fund management approach ", the boiler subsidy detailed as follows:
1, rural areas electricity instead of coal subsidies
The household equipment purchase and install (including line transformation indoor) 85% of investment subsidies, the maximum subsidy per household amount not more than 7400 yuan, the provincial and city and county respectively 50%, the rest borne by the users themselves.
Residents give electricity for heating 0.2 yuan / kwh subsidies, provincial, city and county average bear, the highest household electricity 10,000 kwh subsidies, subsidies and standards tentatively scheduled for three years.
2, substitution of gas for coal in rural areas subsidy standards
The household gas equipment purchase and install the 70% investment subsidies, the maximum subsidy per household amount not more than 2700 yuan. Provincial cities and counties and respectively 50%, the rest borne by the user.
Heating gas for customers who use 1 yuan / cubic meter of subsidy per household per year up to 1200 m3 gas subsidies, provincial, city and county average bear, subsidies and standards tentative three years.
Given the highest building in the village of pipelines family home investment subsidies of 4,000 yuan, 1000 yuan assume the provincial, city and county to bear 3,000.
3, coal-fired boiler subsidy governance standards
Subsidies for coal-fired boilers, eliminate subsidies, a separate ban demolition of 30,000 yuan / tons of steam, the implementation of clean energy transformation of 80,000 yuan / tons of steam.
4, thermal power shutting down out of subsidies
Provincial for shutting down the unit by 300 yuan / kilowatt award given up, have been included in the national "Thirteen Five." Plan for shutting down the unit, illegal construction unit, run-of-life choice except unit and power capacity index trading.
